| Grated Parmesan cheese | 50 g |
| Fresh parsley, finely chopped | 1 handful |
For the Beef Bolognese Sauce
| Ingredient | Amount |
| Ground beef | 500 g |
| Medium onion, finely chopped | 1 |
| Garlic cloves, minced | 2 |
| Tomato sauce or tomato passata | 700 g |
| Tomato paste | 2 tablespoons |
| Dried oregano | 1 teaspoon |
| Dried basil | 1 teaspoon |
| Olive oil | 2 tablespoons |
| Salt | To taste |

Step-by-Step Instructions
1. Cook the Spaghetti
Bring a large pot of generously salted water to a boil.
Add the spaghetti and cook according to the package directions, reducing the cooking time by about 2 minutes. The pasta should remain slightly firm because it will continue cooking in the oven.
Drain the spaghetti well and set it aside. Do not overcook the pasta at this stage, as soft spaghetti can become mushy after baking.
2. Prepare the Beef Bolognese Sauce
Heat the olive oil in a large skillet or sauté pan over medium heat.
Add the chopped onion and minced garlic. Cook for about 3 minutes, stirring occasionally, until the onion becomes soft and fragrant.
Add the ground beef and cook until browned, breaking it apart with a wooden spoon as it cooks.
Once the beef is nicely browned, stir in the tomato paste and cook for about 1 minute.
Add the tomato sauce, dried oregano, dried basil, salt, and freshly ground black pepper.
Stir everything together and bring the sauce to a gentle simmer.
Reduce the heat to low and simmer for about 15 minutes, stirring occasionally. The sauce should become slightly thicker and richly flavored.
3. Preheat the Oven
Preheat your oven to 200°C / 400°F.
Lightly grease a large oven-safe baking dish with a little olive oil or cooking spray.
4. Combine the Pasta and Sauce
Add the cooked spaghetti to a large bowl or directly into the skillet if there is enough room.
Pour about three-quarters of the Bolognese sauce over the spaghetti.
Toss gently until the pasta is evenly coated with the sauce.
This step helps ensure that every strand of spaghetti absorbs the rich tomato and beef flavors.
5. Assemble the Pasta Bake
Transfer the sauced spaghetti to the prepared baking dish and spread it into an even layer.
Spoon the remaining Bolognese sauce over the top.
Sprinkle the shredded mozzarella evenly over the entire surface.
Finish with the grated Parmesan cheese.
Make sure the cheese is distributed evenly so that every serving gets a delicious golden, cheesy topping.
6. Bake Until Golden and Bubbling
Place the baking dish in the preheated oven.
Bake for approximately 15–20 minutes, or until the cheese has completely melted and the top is lightly golden and bubbling.
For a more deeply golden topping, you can place the dish under the broiler for the final 1–2 minutes. Watch it carefully because the cheese can brown quickly.
7. Garnish and Serve
Remove the baked spaghetti from the oven and let it rest for about 5 minutes.
Sprinkle generously with freshly chopped parsley.
Serve hot, spooning portions directly from the baking dish.
Best Tips for Perfect Baked Spaghetti
Cook the spaghetti slightly less than you normally would. Since the pasta continues cooking in the oven, starting with al dente spaghetti helps prevent a soft or mushy texture.
Allow the Bolognese sauce to simmer for at least 15 minutes. This gives the tomato sauce time to develop a richer flavor and prevents the finished casserole from becoming watery.
For the best cheese topping, use freshly shredded mozzarella when possible. It melts beautifully and creates a stretchy, golden layer.
Let the casserole rest for a few minutes after baking. This makes it easier to serve and allows the sauce and cheese to settle slightly.
Best Ingredient Options
For the beef, choose ground beef with enough fat to provide flavor without making the casserole excessively greasy. An approximately 80–90% lean ground beef works well.
For the tomato base, tomato passata creates a smooth sauce, while a chunky tomato sauce gives the casserole a more rustic texture.
Mozzarella provides the stretchy, creamy topping, while Parmesan adds a deeper savory flavor. Using both cheeses gives the best balance.
Fresh parsley adds color and freshness after baking. You can also use fresh basil if preferred.
Recipe Variations
For a creamier baked spaghetti, stir a small amount of cream cheese or heavy cream into the Bolognese sauce before combining it with the pasta.
For extra vegetables, add finely diced bell peppers, mushrooms, zucchini, or grated carrots to the sauce along with the onion.
For a spicy version, add a pinch of crushed red pepper flakes to the tomato sauce.
For a richer cheese topping, combine mozzarella with a little shredded cheddar or provolone.
You can also replace the spaghetti with penne, rigatoni, or another short pasta shape. The recipe works especially well with pasta that holds plenty of sauce.
What to Serve With Baked Spaghetti Bolognese
Serve this cheesy pasta bake with a simple green salad dressed with olive oil and lemon juice for a fresh contrast to the rich sauce.
Warm garlic bread is another excellent choice, especially for soaking up any extra tomato and beef sauce.
For a lighter side dish, steamed broccoli, roasted zucchini, or green beans pair beautifully with the baked spaghetti.
Make-Ahead Instructions
The casserole can be assembled several hours ahead of time.
Prepare the pasta and Bolognese sauce as directed, combine them, and transfer everything to the baking dish. Add the mozzarella and Parmesan topping, then cover and refrigerate.
When ready to bake, remove the dish from the refrigerator and allow it to sit at room temperature for approximately 15–20 minutes.
Bake at 200°C / 400°F until heated through and the cheese is melted and golden. A refrigerated casserole may need several additional minutes in the oven.
Storage
Allow leftovers to cool before transferring them to an airtight container.
Store in the refrigerator for up to 3–4 days.
For the best texture, keep individual portions in airtight containers so they can be reheated easily.
Reheating
To reheat individual portions, place the spaghetti in a microwave-safe dish and heat until hot throughout, stirring halfway through if necessary.
For a larger portion, cover the baking dish with aluminum foil and reheat in a 180°C / 350°F oven until warmed through.
If the pasta looks slightly dry after refrigeration, add a small splash of tomato sauce or water before reheating.
Freezing
Baked spaghetti can be frozen either before or after baking.
For best results, assemble the casserole without baking, cover it tightly, and freeze.
When ready to use, thaw it overnight in the refrigerator before baking.
You can also freeze cooked portions in airtight freezer-safe containers for up to approximately 2–3 months.
Common Mistakes to Avoid
Avoid fully cooking the spaghetti before baking. Overcooked pasta can become soft and lose its texture in the oven.
Do not add too much sauce at once without tossing the pasta. Evenly coating the spaghetti helps distribute the flavor throughout the casserole.
Avoid using an overly watery tomato sauce. A sauce that is too thin can make the finished dish watery.
Do not skip the resting time after baking. Allowing the casserole to sit for a few minutes helps the cheese set slightly and makes serving easier.
Be careful when broiling the cheese. It can go from golden to burnt very quickly.
